Exterior mirror cover (both upper and lower plastic plates) fell off. There was little/no damage, they just have horrible clips. Be sure to put a dab of silicone or other removable adhesive on yours. The top cover was $60 and the bottom ones (there may be 2, but Toyota's diagrams are confusing) looked similar in price. The top is needed so water does not enter some wiring harnesses in the mirror. Overall, this was a bummer and a hassle.

Ignition coil 1 was failing during light acceleration. Reported error code was misfire in cilinder 1. Once deleted it didn't show up again, even when the problem was still there physically. Dealer misdiagnosed it first as dirt in the intake and injectors, so a cleaning of the intake valve and injectors was performed first, with no results, but charged for it. After more diagnosis, they found the ignition coil for cilinder one defective, and was replaced with the next one in the combustion cycle as recommended by Toyota. Problem was solved.

Windshield cracked because of heat. Noticed tiny crack in the windshield, which grew into a foot-long crack. Seems like a defect because many other Prius drivers have reported windshield issues/cracking not involving rocks or accidents.

Rattle in dash finally fixed after multiple attempts. There is no recall on it, or service bulliten, but there is an issue with some 2016 Prius with the rattle. While in for the problem I googled it and shared the results with the technician. He removed the part to see if the rattle went away, which it did, and ordered a vent part. Once a new one was installed the problem was solved.

The dealer stated that the exhaust heat recovery system valve failed, causing a coolant leak into the catalytic converter. Requires exhaust system replacement for the affected valve. 3rd party, an Independent shop, mentioned that the part is a common fail point for gen 4. The only symptom was a chronic low coolant, slow leak. Over time this will damage the cat if the problem is ignored by topping off the fluids.
